IIS queries are disabled by default, and can be enabled with the
`--collector.process.iis=true` flag.
These WMI queries are suspected to be one source of virtual memory leaks
in the exporter.
These WMI queries are also responsible for timeouts on some hosts.

This fix ensures that network stats for containerd on Windows are successfully collected. Before this change, other container stats such as CPU and memory are successfully collected, but network stats are failing for containerd.
The root cause is that the code for collecting network stats was originally written to work with docker which relies on v1 schema. After dockershim removal as Kubernetes's container runtime, containerd adoption has increased and this error is more frequently encountered when using containerd as the runtime. containerd uses v2 schema whereby the network stats need to be queried from the HNS component.

Perflib often exposes duplicate IIS entries, suffixed with '#' and a
number (I.E. iis_site_name#1).
These duplicate entries were causing the exporter to fail scraping due
to duplicate metrics.
Based on user feedback, the entry with the highest suffix
value is kept, with other duplicate entries discarded.
E.G. Given the following list of site names, "Site_B" would be
discarded, and "Site_B#2" would be kept and presented as "Site_B" in the
collector metrics.
[ "Site_A", "Site_B", "Site_C", "Site_B#2" ]

Collector builder functions are only used internally in the `collector`
package, and shouldn't needlessly be exposed as part of the package API
to downstream clients.

Behaviour of init functions has been centralised in `collector/init.go`,
and can be called during exporter startup. This allows the exporter to
control the timing of collector initialisation, rather than relying on
the import & `init()` method.
This should reduce unexpected behaviour arising from the use of
`init()`, such as #551.

Bumps [github.com/alecthomas/kingpin](https://github.com/alecthomas/kingpin) from
v2.2.6 to v2.3.2.
This also changes the upstream package name from
gopkg.in/alecthomas/kingpin.v2 to github.com/alecthomas/kingpin/v2 which
is required by the upstream exporter-toolkit package.
